Aspalathus cephalotes subsp. violacea bluish violet and white flowers are borne in short spikes or stem-tip heads. The keel is silky, as is the calyx with lance-shaped, toothed lobes. In picture the banner petals of the flowers are pale and longitudinally lined near the base, bluish purple near the margins like the darker wing petals. Flowering occurs from late winter to spring.
The leaves are three-foliolate, the leaflets linear or thread-like, dark-green and sparsely hairy. Leaflets may be terete, i.e. thinly cylindrical or slightly flattened, becoming from 4 mm to 10 mm long (Manning, 2007; iSpot).
